Won't output Gui to FrameBuffer, ask for X Server.

I am developing QT-ARM-Code on my Ubuntu Linux box. I want the GUI to output to the FrameBuffer.

I made a very simple application compile it under the Arm Compiler, download it to my arm system and run it and it says ArmTest: cannot connect to X server.

I am running it using "./ArmTest -qws" but it still wants to connect to the X Server instead of my FrameBuffer.

What am I doing wrong? Here is my very simple code.

==========================================

#include <QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
return a.exec();
}
